If your keyboard linked three lights thats mean its not a problem of motherboard check your RAM or Connection of HDD.

no diplay in this board give me sme notes to chag ic.what ic i did change

with no ram you will get beeps that confirms your processor is working (as it cant detect ram) you could be using the wrong speed or type, also as Ghoaliass stated, if your using a couple of modules try one at a time, if it fails on the first, remove the stick and try anther one and so on until you at lease get a bios screen :)

Hop-e this helps,

system is on but no display. yes i did heard sound 3 beep sound from the motherboards.

that means a short in contacts on memory slot, or a component on board melting down.
If this happened it is possible that the motherboard is faulty.
If you are lucky the motherboard will read memory on one of memory slots, more likely it wont read memory at all.
Due to the cost of labor required to test and fix the motherboard usually it is worth replacing it rather than fixing it.
A P4 motherboard starts from around $50, on Ebay you can find tested and guaranteed second hands from $20.

As you probably know 3 long beeps on an Intel motherboard is memory failure. Even if RAM is good your Motherboard may have problems in reading your ram module.
If you are using a PCI or AGP video card try also removing and putting back video card, video adapters use shared RAM and can give you troubles with RAM.
Always perform all maintainance on motherboard with power unplugged and avoid to touch contacts and circuits with your finger.
If the 1GB module is new, verify with seller that your motherboard support this memory, some motherboard do not support double density RAM.

That board only supports ddr ram not the newer ddr2. It will run pc1600/pc2100/pc2700 up to 2 gigs. So make sure you have the right ram for it. Also what cpu are you using?.

intel 845 gvsr motherboard have two most problem

vrm circuit fail IC ADP3168 {between the cpu and core volt connector}
f7338 mosfet ic fail {between the memory slot and ide connector}

first remove ur memory card and and just wipe the contacts with ur nail or )size sand paper slowly it would work up

try a new power supply
